Which species is not a variety or type of Holly?

The species Itea virginica is indeed not a type of Holly, while the others listed are all members of the Ilex genus, commonly known as Holly.

Ilex crenata, commonly referred to as Japanese Holly, is a true Holly species known for its small leaves and versatility in landscaping. Ilex verticillata, or Winterberry Holly, is another species recognized for its attractive red berries and deciduous nature, making it popular for winter interest in gardens. Ilex cornuta, known as Chinese Holly, features spiny leaves and is cultivated for its ornamental use and resistance to cold temperatures.

In contrast, Itea virginica is a different genus altogether, belonging to the Iteaceae family, and is commonly known as Virginia Sweetspire. It is recognized for its fragrant, white flower spikes and is often used in landscape plantings for its lovely fall color and ability to thrive in wet conditions. Understanding these distinctions clarifies why Itea virginica stands apart from the other species listed.
